Extensible Markup Language

From Fiswiki

XML (Extensible Markup Language) A general-purpose markup language for creating special-purpose markup languages. It is capable of describing many different kinds of data. NOTE: Its primary purpose is to facilitate the sharing of data across different systems, particularly systems connected via the Internet.

It is classified as an extensible language, because it allows the user to define the mark-up elements. XML's purpose is to aid information systems in sharing structured data, especially via the Internet, to encode documents, and to serialize data.
